Abstract
A method is for detecting the route taken by a motor vehicle in a particular zone within which the number of lanes increases or decreases. The method includes recording position data characterizing the position of the motor vehicle in relation to the lane separation lines marked on the road and calculating, via a recurrent neural network, at least one parameter for the detection of the particular zone, the recorded position data being supplied as input to the recurrent neural network

A method for detecting, on a road being travelled by a motor vehicle, a singular zone within which a number of traffic lanes increases or decreases, the method comprising:
- reading position data characterizing a position of the motor vehicle with respect to lane separation lines marked on the road;
- and
- computing, by a recurrent neural network, at least one parameter of detection of a singular zone, the read position data being delivered as input to said recurrent neural network.
A method for parameterizing a computer to assist with keeping a motor vehicle in a traffic lane of a road, comprising:
- carrying out, in a real or virtual environment, a training trip during which a test vehicle is driven over road segments comprising singular zones, and during which are stored position data relating to a position of the test vehicle with respect to the lane separation lines marked on the segment of road travelled and information indicating whether said road segment is a singular zone within which the number of traffic lanes increases or decreases;
- building a database containing, for various successive times, said position data and said stored information;
- training a recurrent neural network making it possible to determine at least one parameter of detection of a singular zone of the road within which the number of traffic lanes increases or decreases, said recurrent neural network receiving said database by way of training datum;
- and
- saving the recurrent neural network to the computer of the motor vehicle.
